Cyberbullying is extreme, intentional bullying that happens online.

Writing an email to a friend when you're angry or blocking someone on Facebook aren’t always kind things to do, but these actions aren't cyberbullying.

Some examples of cyberbullying are:

• Creating a blog or website to make fun of someone.
• Posting someone's personal information in a public place online.
• Sending repeated messages to someone after you've been asked to stop.
• Stealing or guessing someone's password and using it to log in to their email account.
• Encouraging others to gang up on a victim to tease, harass, or embarrass them.
• Pretending to be someone else online.

If you're being bullied online, it's a good idea to block the cyberbully from emailing or instant messaging you, and then tell an adult you trust, like a parent or a teacher.

Severe cyberbullying, such as making threats to kill or harm someone else or posting personal information online, is illegal and can lead to fines or time in jail.

If you're being severely bullied online, it's important save all emails and messages from the bully, so this evidence can be used to make the cyberbully stop.
